我们使用甚高频无线电遥测技术研究了斯里兰卡南部雅拉保护区建筑群及其周围的10头大象的测距模式。所有被追踪的大象都显示出类似的测距模式。与印度报告的栖息地相比，观察到的栖息地范围较小(平均=115.2+/-64.0kM(2))，这可能是对高栖息地生产力和丰富的常年水源的反应。大象对它们的活动范围表现出高度的保真度。栖息地的核心区相对较大，表明栖息地得到了密集的利用。没有观察到地理上明显的季节变化或迁徙行为。主场范围重叠度很高，没有领土。雄性求偶范围比非求偶范围大得多，可能是寻找配偶的标志。大多数大象生活在保护区内和保护区外，这表明保护区外的资源对它们的生存非常重要。因此。将大象转移：并将大象限制在保护区将不利于它们的生存，因为这限制了资源的获取。亚洲象的活动模式表明，保护该物种需要在保护区内外对它们进行管理。(C)2007年德国Gesellschaft毛皮Saugetierkunde。由Elsevier GmbH出版。版权所有。
We studied the ranging patterns of 10 elephants in and around the Yala protected area complex, southern Sri Lanka, using VHF radio telemetry. All tracked elephants displayed similar ranging patterns. The observed home ranges were small (mean = 115.2 +/- 64.0 km(2)) relative to reported home ranges in India, possibly in response to high habitat productivity and abundant perennial water sources. Elephants showed high fidelity to their ranges. Home ranges had relatively large core areas, suggesting intensive use of habitat. No geographically distinct seasonal ranges or migratory behavior was observed. Home range overlap was high, and territoriality was absent. Male musth ranges were considerably larger than non-musth ranges and may signify mate searching. Most elephants ranged both in and outside protected areas, suggesting that resources outside protected areas were important for their survival. Thus. translocating:, and restricting elephants to protected areas will be detrimental to their survival, as it limits resource access. The ranging patterns of Asian elephants suggest that conservation of the species requires their management both in and outside protected areas. (C) 2007 Deutsche Gesellschaft fur Saugetierkunde.
